yeah i know how you feel. Im 14 and when i was 12-13 i was workin on making my traxxas stampede 4x4. It takes alot of parts and i couldnt drive and 30 min. drive to the hobby store to get them and needless to say my parents werent just jumping at the chance to take me. To make it worse the hobby store didnt always have what i wanted so multiple trips were needed. I quickly learned that if you call ahead most stores will put aside the part you need so when you get there it will still be there and they will most always go look to see if they have it. I know theres only so much you can do when it comes to things like this but every little bit helps. And since you probably wont be doing anything while you waiting to go get that part go look to see if you can find something that will work the same way that part will. Or see if there is something else you can do on the project since you have all that time.
